Some Sigma DP1 rumors

I mentioned already that I like the new Sigma DP1 (I don't have it, but I like it). Now it seems that Sigma will come up with DP2 and DP3 models (one of them with zoom).

How does this apply to a Nikon rumors blog? If Sigma DP1 is successful (and I think it will be), I expect Nikon to come up with something similar. I still love and use my Leica Minilux but I will be happy to replace it with a DP1 or a Nikon equivalent.
